OKI Introduces High Switching Current Reed Switch
- This device achieves industry-first 5 A maximum carry current and 2 A
maximum switching current with glass tube length of 16.5 mm -
TOKYO -- October 10, 2013
OKI Sensor Device, an OKI Group company that develops, manufactures, and sells
reed switches, has introduced the ORD872, a high-current reed switch housed in
a glass tube measuring 16.5 mm in length and boasting an industry-first
maximum carry current of 5 A and maximum switching current of 2 A. Samples
will be available from October 30, with production devices slated to begin
shipping by December 1. OKI Sensor Device has set sales targets of 700,000
units for fiscal 2014, ramping up to 6,000,000 units in fiscal 2017. Sales
will focus on buyers in the automotive and industrial equipment markets
throughout the world.
Since 2006, OKI Sensor Device has produced reed switches with maximum carry
current of 2.5 A for controlling LED stop lamps in compact passenger vehicles.
Mid-sized and larger automobiles are generally equipped with mechanical
switches capable of handling large control currents. However, mechanical
switches present various drawbacks, including short service life and contact
failures due to dust adhesion. The ORD872 developed by OKI Sensor Device is
the world’s first reed switch designed for use in mid-sized and larger
automobiles. Sealed in a glass tube, the ORD872 features long service life and
is capable of withstanding harsh service environments while providing high
current switching capabilities equivalent to mechanical switches.
The ORD872 incorporates a new cobalt alloy wire to achieve a maximum carry
current ^ of 5 A and a maximum switching current of 2 A^*, both industry-first
achievements. It features a glass tube measuring 2.8 mm in diameter and 16.5
mm in length. The ORD872 can handle twice the current of conventional products
of the equivalent glass tube length from other companies. Coupled with a
projected service life of one million switching operations—equal to the
service life of conventional products—the ORD872 sets new standards for
reliability and performance.
“We are excited to announce our pioneering new high current reed switch. We
are re-defining standards for reliability and performance of reed switches by
introducing a new device that is suitable for an impressive range of
applications,” says Yuki Ushida, President of OKI Sensor Device. “The newly
developed ORD872 reed switch is ideal for use including industrial devices
that incorporate mercury reed relays ^ and high-capacity position sensors. As
an alternative to mercury reed relays, the ORD872 also helps reduce
LEDs consume less power and generate lower environmental impact than
conventional incandescent lamps. Use of LEDs in automobile stop lamps and
interior lamps has grown in recent years, spurring growing use of long-lived,
environmentally-resistant reed switches for LED control. Demand for reed
switches for LED control in automobiles is expected to continue growing in the
years to come.
The new “ORD872” will be exhibited at electronicAsia 2013 to be held in Hong
Kong between October 13 and 1.6.
